Convolutional Neural Network from scratch

Live Demo

Objective of this work was to write the Convolutional Neural Network without using any Deep Learning Library to gain insights of what is actually happening and thus the algorithm is not optimised enough and hence is slow on large dataset like CIFAR-10.
This piece of code could be used for learning purpose and could be implemented with trained parameter available in the respective folders for any testing applications like Object Detection and Digit recognition.

It's Accuracy on MNIST test set is above 97%.

Architecture

INPUT - CONV1 - RELU - CONV2 - RELU- MAXPOOL - FC1 - OUT

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

• Numpy - Multidimensioanl Mathematical Computing
• Matplotlib - Used to plot Graph
• Pickle - Used to save trained models/object
• MNIST Dataset - Dataset for Digit Recognition
• CIFAR-10 Dataset - Dataset for Object Recognition

Followings are also required if working/testing on the app.py

• Flask - A microframework for Python
• Gunicorn - A Python WSGI HTTP Server for UNIX
• OpenCV - An open-source library that includes several hundreds of computer vision algorithms

Directories

• CIFAR-10: Object detection with CIFAR-10
• MNIST: Handwritten Digits Recognition with MNIST

Installing

• Clone the repository

git clone https://github.com/zishansami102/CNN-from-Scratch

• Downlad the dataset and copy that to it's corresponding folder(CIFAR-10/MNIST).
• Move into the required directory (/CNN-from-Scratch/MNIST or /CNN-from-Scratch/CIFAR-10) and then run the following command to start training model

python train.py

Output:

• To load pre-trained models, change the pickle filename from 'output.pickle' to 'trained.pickle' in run.py: line No. - 30-31 and comment out the training part form the code in run.py: line No. - 42-111

Application Testing/Running

• In the the directory /CNN-from-Scratch run the following command.

python app.py

App will start running on the local server http://127.0.0.1:5000 as shown below :
